Check out DSpace from SVN
To check out DSpace, first determine the version of DSpace you want to install.
A few tips on how the DSpace SVN repository is organized / managed:
- /tags/ - Tagged versions represent*stable, official releases* of DSpace software. If you want to install a supported version of DSpace, find the appropriate tag to checkout.
- /branches/ - Branches are used for development of new minor, bug-fix releases (e.g. 1.4.2, 1.5.1). They should be considered semi-stable, but are not recommended unless you plan to help in development work.
- /trunk/ - Trunk is used for development of the next major version (e.g. 1.4, 1.5, 2.0). It should be considered highly unstable, and is not recommended unless you plan to help in development work.
Once you've chosen your version, check it out as follows (the below example is for DSpace 1.5):
svn co https://scm.dspace.org/svn/repo/dspace/tags/dspace-1_5 /some/where
Where "/some/where" is a path on the local file system that may be relative or absolute.
This will check out all of the DSpace modules.
Initial Build and Installation
To build DSpace (with PostgreSQL as the database):
Navigate into the directory called "dspace" within your svn checkout.
Execute Maven using the following command
Note, one previously had to execute Maven with "assembly:assembly" as an option, this is no longer necessary. Other options for executing maven include designating the database to be used, this can be executed wih the following additional option.
mvn -Ddb.name=[postgres|oracle] package
This might take a while as required JARs etc are downloaded.
Now you should have a DSpace build in
. Set up a PostgreSQL database as usual. Edit
dspace/target/dspace-1.5-SNAPSHOT.dir/config/dspace.cfg as required. Run:
You may see errors like this, but these don't matter:
[java] log4j:ERROR Could not read configuration file [file:config/log4j-console.properties]. [java] java.io.FileNotFoundException: file:config/log4j-console.properties (No such file or directory) [java] at java.io.FileInputStream.open(Native Method) [java] at java.io.FileInputStream.<init>(FileInputStream.java:106) ....
as long as you see BUILD SUCCESSFUL you should be OK.
In your DSpace install directory (by default
/dspace), you should see a
webapps dir. Copy these to your Tomcat's
Editing the source is now possible using any tools you like.
Using Eclipse is actually very easy if you're on 3.3 and have Subclipse installed. Just create a Java project, specify 'create project from existing source' and point it at
/path/to/src, i.e. the directory with
dspace-api etc. in it. Eclipse picks up the source directories and JARs, and even the SVN source control info. You might like to change Eclipse's build directory and remove duplicates and
dspace-*.jar from the JARs in the build path, but as far as source editing with code completion goes you're good.
To deploy your changes (you'll probably want to set up a script to do this!)
$CATALINA_HOME/bin/shutdown.sh cd /path/to/your/src/dspace mvn package cd target/dspace-1.5-SNAPSHOT.dir ant -Dconfig=/dspace/config/dspace.cfg update rm -r $CATALINA_HOME/webapps/dspace-* cp -r /dspace/webapps/* $CATALINA_HOME/webapps/ $CATALINA_HOME/bin/startup.sh
mvn package will overwrite the dspace.cfg in
Keeping up to date with DSpace SVN
In the top level of your checked out DSpace (i.e. the
/path/to/your/src dir) do:
You should see messages about what's being updated. If you see 'C' or messages about conflicts by any of the files, you will need to go to the files where there were conflicts and resolve them. See the section entitled "Resolve Conflicts (Merging Others' Changes)" in the SubVersion documentation.
Creating a patch file
NB: Read Code Contribution Guidelines before submitting a patch
To create a patch for all changes, run
svn diff -u > mypatch.txt
To create a patch for only certain files, run
svn diff -u path/to/files > mypatch.txt
Applying a patch file
The easiest way to apply a patch is by using the Linux
patch command. For information on what the
patch command does and all of its options, take a look at
man patch from a Linux machine.
TODO: More detail needed
In general, you most likely will want to run a command similar to the following from your [dspace-source] directory (but see the Important Hints below, before running anything!):
patch -p0 < mypatch.txt
- It's highly recommended to add the
--dry-runoption initially, in order to test your command first, since not all patches are created equal!
--verboseoption is sometimes helpful in understanding what applying the patch is actually doing.
